摘要/Abstract

摘要： 为充分利用新疆地区自然资源,达到“就地取材”“以灾制灾”的目的,采用天然沙漠砂替代混凝土骨料并在胶凝材料中加入粉煤灰、硅灰进行混凝土配合比优化研究。首先,通过正交试验,研究粉煤灰掺量、水胶比、灰砂比和减水剂掺量四个因素对沙漠砂混凝土性能的影响,结合天然沙漠砂混凝土抗压及劈裂抗拉强度进行了极差、因素指标和方差分析。随后,采用单因素试验法探究了硅灰掺量对天然沙漠砂混凝土力学性能和工作性能的影响。结果表明,天然沙漠砂混凝土最优配合比为粉煤灰掺量20%(质量分数,下同)、水灰比0.33、灰砂比1 ∶2、减水剂掺量0.8%。硅灰的加入能显著提升沙漠砂混凝土的抗压强度,但会降低沙漠砂混凝土的工作性能,加入10%硅灰时,沙漠砂混凝土的力学性能和工作性能最佳。

Abstract: In order to make full use of natural resources in Xinjiang and achieve the purpose of “local materials” and “disaster prevention”, this paper uses natural desert sand to replace concrete aggregate and adds fly ash and silica fume to cementitious materials to optimize the mix ratio of concrete. Firstly, the effects of four factors, such as fly ash content, water-binder ratio, cement-sand ratio and water reducer content, on the performance of desert sand concrete were studied by orthogonal test. The range, factor index and variance analysis were carried out in combination with the compressive and splitting tensile strength of natural desert sand concrete. Subsequently, the effect of silica fume content on the mechanical properties and working performance of natural desert sand concrete was investigated by single factor test. The results show that the optimal mix ratio of natural desert sand concrete is fly ash content of 20% (mass fraction, same below), water-cement ratio of 0.33, cement-sand ratio of 1 ∶2, and water reducer content of 0.8%. The addition of silica fume can significantly improve the compressive strength of desert sand concrete, but it will reduce the working performance of desert sand concrete. When 10% silica fume is added, the mechanical properties and working performance of desert sand concrete are the best.

Key words: desert sand concrete, fly ash, silica fume, orthogonal test, mechanical property, mix ratio, solid waste utilization
